●

Watch for bystanders and never allow
anyone to be under, or to reach through the
booms while operating the aerial platform.

Pinch points may exist between moving

components. Death or serious injury can

result from becoming trapped between

components, buildings, structures, or other

obstacles. Make sure there is sufficient

clearance around the machine before

moving the chassis, booms, or platform.

Allow sufficient room and time to stop

movement to avoid contact with structures

or other hazards.

Keep ground per son nel from un der the plat form
when the plat form is raised.

Se cure all ac ces so ries, con tain ers, tools, and
other ma te ri als in the plat form to pre vent them from
ac ci den tally fall ing or be ing kicked off the platform.

Al ways look in the di rec tion of travel. Drive with
care and at speeds com pat i ble with the work-place
con di tions. Use cau tion when driv ing over rough
ground, on slopes, and when turning.

Do not en gage in any form of horse play or stunt
driv ing while op er at ing the X33RT / X27RT.

Do not per mit rid ers on the ma chine any place other
than on the plat form.

Re move all loose ob jects stored in or on the ma ­chine, par tic u larly in the plat form. Re move all ob ­jects which do not be long in or on the machine.

Never steady the plat form by po si tion ing it against
an other plat form.

Do not op er ate an X33RT / X27RT that is dam ­aged or not func tion ing prop erly. Do not use the RT
un til the ma chine has been re paired by a qual i fied
main te nance person.

fol low ing guidelines apply:

1. Where possible, place the work platform over
a roof or walking structure to do the transfer.

2. Transfer your anchorage from one structure
to another before you step across.

3. Remember, you might be departing the work
platform to a structure where fall arrest is
required.

4. Do not climb over or through the guardrails.
Use the platform entrance.

All plat form oc cu pants MUST wear and use fall re ­straint. At tach fall re straints to the plat form lan yard

Fire Prevention

Never op er ate your RT near a flame or spark. Hy ­drau lic oil and gas o line are flam ma ble and can ex ­plode.

■

Engine and Fuel Handling Precautions

Engine exhaust contains carbon monoxide,
a poisonous gas that is invisible and
odorless. Breathing engine exhaust fumes
can cause death or serious illness. Do not
run the engine in an enclosed area or
indoors without adequate ventilation.

Only re fuel your RT out doors in a clear area void of
gas fumes or spilled gas.

Never re move the fuel cap or re fuel a gas o line en ­gine while the en gine is run ning or hot. ALWAYS al ­low the en gine to cool be fore re fu el ing. Never al low
fuel to spill on hot ma chine components.

DO NOT smoke or permit open flames while
fueling or near fueling operations.

Main tain con trol of the fuel filler noz zle when fill ing
the tank.

Tighten the fuel tank cap se curely. If the fuel cap is
lost, re place it with an ap proved cap from Snor kel.
Use of a non-ap proved cap with out proper vent ing
may re sult in pres sur iza tion of the tank.

Never use fuel for clean ing pur poses.

For die sel en gines, use the cor rect fuel grade for
the op er at ing sea son.

■

Batteries

Charge bat ter ies in a well ven ti lated area free of
flame, sparks, or other haz ards that might cause
fire or ex plo sion.

Batteries give off hydrogen and oxygen that
can combine explosively. Death or serious
injury can result from a chemical explosion.
Do not smoke or permit open flames or
sparks when checking batteries.

Battery acid can damage the skin and eyes.
Serious infection or reaction can result if
medical treatment is not given immediately.

Alarms

There are two alarms on an RT. One is lo cated in
the plat form con trol box, the other is lo cated in the
ground con trol box.

The alarms are con nected in par al lel, they both
emit the same pat tern of sound at the same time.
The dif fer ent alarm sound pat terns are shown in

2. Safety Devices

The DRIVE (forward) and the platform-lowering
alarms beep at one beep per second. DRIVE (re­verse) beeps at two beeps per second. The level
sensor alarm is a high-low warbling sound.

The LOAD SENSING alarm also emits a high-low
warbling sound, as does the alarm that sounds
when the scissor stack stops descending at 1
metre from stowed position

❑ Load sensing system

The load sensing system sounds an alarm and
illuminates a lamp to warn the operator that the
platform is overloaded.

The alarm will sound and the overload light (see
figure 2.3) will illuminate as soon as the overload
point is reached.

NOTE 2:

The joystick must be released and then reapplied
once the preset time period has elapsed before
the platform will continue to descend.

❑ High temperature

The high-temperature alarm warns you that the en­gine is overheating. When the alarm sounds you
should immediately lower the platform completely
down then turn the engine off until the condition
that caused the overheating has been corrected.
(See Automatic Shut-Offs & Circuit Breakers chap­ter 5 for more information.)

❑ Low oil pressure

The low pressure alarm warns you that the engine
oil pressure is near the lowerlimit for safe operation
of the engine. When the alarm sounds you should
immediately lower the platform completely down
then turn the engine off until the condition that
caused the low oil pressure has been corrected.
(See Automatic Shut-Offs & Circuit Breakers chap­ter 5 for more information.)

Figure 2.3 - Platform Overload Light

NOTE:
When the alarm sounds all platform movement

[drive forward / reverse and lift up / down is
prevented.
The alarm and function interlock will be active
until the load is reduced.

❑ Lowering

The lowering alarm warns people near an RT that
the platform is coming down and the scissor arm
assembly is closing.

When the plat form is ap proximately 1 metre from
the stowed po sition the plat form will stop low ering
and a warn ing alarm will sound. This alarm will con ­tinue to sound un til the joy stick is re leased and the
preset time pe riod has elapsed.

NOTE 1:

This is intended to prompt, and allow time for the
operator to check that no person has any
appendage in the scissor arm mechanism.

❑ Drive (reverse)

The DRIVE (reverse) alarm alerts people that the

RT is traveling backward along the ground. This

a larm beeps twice as fast as the DRIVE (forward)

❑ Drive (forward)

The DRIVE (forward) alarm alerts people that the
RT is traveling forward along the ground. This
alarm beeps half as fast as the DRIVE (reverse)
alarm.

The wa ter gauge is lo cated on the ground con trol
box. It shows the tem perature of the wa ter-anti­freeze mix ture in the en gine block. The typ ical op ­er at ing-tem per a ture range for Kubota en gines is
180°F to 205°F (82°C to 96°C), both die sel and
gasoline. (See the Au tomatic Shut-Offs & Cir cuit

Amps

●

The oil dipstick is the only way to
accurately gauge if the engine oil level is
correct.

●

Engine oil level should always be between
the lines on the dipstick - never above the
top line or below the bottom line.

Gas o line Die sel

The hy draulic-oil level gauge is on the side of the
hydraulic oil tank. It shows the ac tual level of oil in -

Figure 4.2 - Ammeter Gauge

The AMPS gauge shows the elec tric cur rent from
the al ternator to the bat tery. When the en gine is
running, the nee dle in the AMPS gauge should not
be to the left of 0. Un der nor mal op erating con di­tions, af ter the en gine has been run ning for a few
minutes, the AMPS gauge should read 0.

Engine Oil

Engine oil level is mea sured with a dip stick. Oil ca ­pac i ties given in the Spec i fi ca tions chap ter 3 are
approximate. True val ues will vary from ma chine to
ma chine due to slight vari a tions or mod i fi ca tions
during production.

side the tank. Read it only when the plat form is
completely down. Oth erwise, the lift cyl inders be ­come large res ervoirs for hy draulic oil and the oil
level in the tank will be low. The oil level should be
within ( 0.25 inches, 6.4 mm) of the line.

4. Gauges

■

Hours

Figure 4.5 - Hour Gauge

The HOURS gauge is ba sically an elec tric clock. It
accumulates time only when the en gine is run ning.
The HOURS gauge cannot be reset. An RT-quali­fied ser vice tech nician uses it to tell when it is time
for the pe riodic main tenance listed in the Main te­nance Manual.

Bubble Level

Figure 4.7 - Bubble Level

A bub ble level is lo cated on the plat form side rail,
below the plat form con trol box. Watch the bub ble
level while you set the sta bilisers man ually. Lower
the sta bilisers, one at a time, just enough to cen ter
the bub ble in the cir cle on top of the gauge. When
the bub ble is cen tered the plat form is level and can
safely be raised.

■

Fuel Level (option)

NOTE:

LPG fuel installations are usually fitted post
production and may vary from machine to
machine. It is the operator’s responsibility
therefore, to be aware of how the system is
installed on their individual machine and know
which gauge, (horizontal or vertical) to read.

5. Automatic Shut-offs and Circuit Breakers

■

Automatic Shut-offs

❑ Level sensor

When the level sen sor alarm sounds, au to matic in ­ter locks make it im pos si ble to drive the RT or raise
the plat form. For more com plete in for ma tion see
the Level Sen sor sub sec tion of the Safety De vices
2 chapter.

❑ Engine temperature

engine shuts off. The engine will restart with low
pressure but it will only run a few seconds before it
automatically shuts off again.

❑ Platform height vs. drive speed

When the plat form is over 1.7m (5 6") above the
ground the drive speed is lim ited to its slow est
speed and the en gine revs are also au to mat i cally
low ered.

❑ Dynamic brakes

When you drive an RT down a slope, if the RT be ­gins to coast (out run the drive mo tors) the hy drau lic
sys tem senses the coast ing con di tion. The hy drau ­lic drive mo tors then be come hy drau lic brakes and
the RT is slowed. This ac tion pre vents SRs from
speed ing down grades.

❑ Alternator not charging

Figure 5.1 - Engine Temperature Sensor

There is a tem per a ture sen sor in the en gine. It
mea sures the tem per a ture of the an ti freeze-wa ter
mix ture as the mix ture leaves the top of the ra di a tor
and en ters the top of the en gine. If the tem per a ture
reaches 210(F (99(C) an alarm sounds. If the tem ­per a ture con tin ues to rise, the en gine shuts off
when the tem per a ture reaches 230(F (110(C). The
en gine will not re start un til the tem per a ture drops
below 210(F (99(C).

❑ Engine oil pressure

Figure 5.3 - Alternator Output Shutdown

When the fan belt breaks, or the al ter na tor out put
falls be low a safe level for other rea sons, the en ­gine au to mat i cally shuts off and an alarm sounds.
As long as the RT bat tery is charged you can lower
the plat form, in the usual way, from the plat form
con trol box or the ground con trol box with out the
en gine running.

❑ Stabilisers

The RT can not be driven un less the sta bi lis ers are
com pletely up. If you have just raised the sta bi lis ­ers but the RT will not drive, dou ble check to be
sure all four sta bi lis ers are com pletely up.

Figure 5.2 - Engine Oil Pressure Sensor

There is an oil pressure sensor in the engine. It
measures the engine oil pressure at the oil filter. If
the pressure falls below a safe operating value the

SR3370 & SR2770 – 13184A Rev A page 5 - 1

5. Automatic Shut-offs and Circuit Breakers

❑ Load sensing system

The load sens ing sys tem sounds an alarm to warn
the op er a tor that the plat form is over loaded.

NOTE:

When the alarm sounds all plat form move ment
[drive for ward / re verse and lift up / down is pre ­vented].
The alarm and func tion in ter lock will be ac tive un til
the load is reduced.

❑ Lowering

The low er ing warn ing alarm will ac ti vate and plat ­form de scent will stop ap prox i mately 1 metre from
the stowed po si tion. This alarm will con tinue to
sound and no fur ther plat form move ment will oc cur
un til the joy stick has been re leased for the pre set
pe riod of time.

Circuit Breakers

❑ Main breaker

❑ RCD / ELCB outlet (option)

Figure 5.5 - RCD/ELCB Outlet

The RCD (Re sid ual Cur rent De vice) is lo cated at
the ground and will pro tect against short cir cuits to
earth. When there is a short cir cuit the RCD will
shut down the 230v AC power to the plat form
out let.

To re set the out let dis con nect the power tool lead
from the plat form box and re set the RCD at the
ground.

Figure 5.4 - Main Circuit Breaker

There is only one cir cuit breaker, on a stan dard ,

that is ac ces si ble to the op er a tor. Its pur pose is to

pro tect the elec tri cal cir cuits from elec tri cal over ­loads. When the cir cuit breaker trips (pops out)
push it back in then at tempt to use the RT.

If the cir cuit breaker trips a sec ond time, take the
RT out of ser vice and re fer the prob lem to a qual i ­fied trained ser vice tech ni cian for repair.

If the prob lem per sists call a trained ser vice tech ni ­cian.

switch-cover down, at any time, under any
conditions, and the entire machine stops ­the engine turns off and nothing moves. This
switch must be up for anything on the
machine to work.

2.

Key Switch: This switch works like an
automobile ignition switch. Hold the key at
the start symbol (extreme clockwise position)
until the engine starts then release it to the
on position (bar symbol).Turn the key to off
(O) if the platform is to stay in one position
for a long time. That will turn the engine off
and save fuel.

3.

Choke Indicator Light: (gasoline engines
only): This light will be lit while you choke the
engine (see CHOKE below).

3.

Glow-Plug Indicator Light: (diesel engines
only): This light will be on while the glow
plugs are on. Wait, about 30 seconds for the
light to go out before you try to start a diesel.

4.

Choke: (gasoline engines only): Hold the
choke switch up anytime you start a gasoline
engine that is at ambient air temperature (a
cold engine).

4.

Glow Plug: (diesel engines only): This is a
momentary contact switch. Press it up then
release it just before you start a diesel
engine that is at ambient air temperature (a
cold engine). This action automatically
causes glow plugs to come on for 30
seconds to warm the inside top of each
cylinder, thus aiding combustion.

5.

Lift Indicator Light: The platform can be
raised only when this light is lit. When this
light is not lit the platform will not rise
because: the platform is not level, or the
stabilisers are not properly set.

6.

Platform Lift/Lower: Holding this switch up
causes the platform to rise. Pushing this
switch down causes the platform to lower.

7.

Fuel (option): Before starting a dual-fuel
engine set the FUEL switch to gasoline (up)
or LP gas (down) depending on which you
want to use. If you select LP gas, be sure to
open the valve on top the LP gas tank.

NOTE

The EMERGENCY STOP switch on the ground
control box overrides the one on the platform
control box. If the one on the ground control box
is off the RT will not start or run, it does not make
any difference whether the one on the platform
control box is on or off.

2.

Start: Turn and hold the switch to the right to
start the engine. As soon as the engine
starts, release the switch.

3.

Choke: (gasoline engines only): Press and
hold the switch in anytime you start a

plugs are on. Wait for the light to go out
before you try to start a diesel.

5.

Safety Control: The SAFETY CONTROL
must be squeezed against the JOYSTICK
CONTROLLER to activate the joystick
controller. If the safety control is not
squeezed the joystick controller is
inoperative.

6.

Joystick Controller: If the LIFT/DRIVE
SELECTOR is set to the left (lift function),
pulling the joystick controller backward
causes the platform to rise, pushing the
joystick controller forward causes the
platform to lower. If the LIFT/DRIVE
SELECTOR is set to the right (drive
function), pushing the joystick controller
forward causes the RT to move forward,
pulling the joystick controller backward
causes the RT to move backward. The
further you push or pull the controller the
faster the motion (except lowering-it occurs
at one speed only).

6. Controls

7.

Steering: The rocker switch on top of the
JOYSTICK CONTROLLER turns the front
wheels left or right depending upon which
side of the switch you press.

NOTE

The wheels do not return to straight ahead, after
a turn, the way automobile wheels do. You must
use the STEERING switch to straighten the
wheels after a turn.

8.

Lift/Drive Selector: When this switch is set
to the left the JOYSTICK CONTROLLER
becomes a lift/lower controller to raise or
lower the platform. When this switch is set to
the right the JOYSTICK CONTROLLER
becomes a drive controller to drive the RT
forward or backward. The RT will not drive
and lift at the same time.

9.

Speed: Set the switch to turtle (slow) when
you are working in close quarters or if you
are new to the machine. Setting the switch to
rabbit (fast) doubles the top speed of the RT.

10.

Lift Indicator Light: The platform can be
raised only when this light is lit. When this
light is not lit the platform will not rise
because: the platform is not level, or the
stabilisers are not properly set.

11.

Drive Indicator Light: The platform can be
driven when this light is lit. When it is not lit
the platform will not drive because with the
platform raised the base is not level or with
the platform raised the axle switches are not
set.

Check to see that the cap  is in place and is tight
(see Fig ure 7.13).

❑ Hydraulic oil level

To check the hy drau lic oil level:

Com pletely lower the plat form. The hy drau lic oil
level should be at the full level ac cord ing to the
gauge  (see Fig ure 7.13) . If nec es sary, add hy -
drau lic oil at the Hy drau lic oil tank cap. See the
Spec i fi ca tions chap ter for type and grade of hy ­drau lic oil.

Hydraulic Oil Leaks

Leaking hydraulic oil can cause burns, fires,
falls (slipping), cuts, and puncture wounds
(if under high pressure). Do not tolerate
hydraulic oil leaks. They are dangerous.

❑ Battery Fluid Level

Batteries emit hydrogen and oxygen,
elements that can combine explosively.
Death or serious injury can result from a
chemical explosion.

DO NOT smoke or per mit open flames or sparks

when check ing bat ter ies.

Note

Units manufactured in New Zealand are typically
fit ted with a "main te nance free" bat tery.

If your unit is not fit ted with sucha bat tery you will
need to do the fol low ing.

page 7 - 4 Rev A SR3370 & SR2770 – 13184A

Do not search for leaks with your hand, use a piece
of card board or wood. Hy drau lic oil leaks are eas ily
vis i ble and can show up any place. Vi su ally in spect

Operating Procedures

This chap ter ex plains how to start and run an RT
that has ei ther a gas o line or die sel en gine. Start ing
a gas o line en gine that is set up to burn LP-only or
dual-fuel is also dis cussed in this chap ter. Read
and un der stand all the pre vi ous chap ters be fore
you be gin to operate an RT

■

Control Stations

An RT can be started and op er ated from the
ground con trol box or from the plat form con trol box.

The ground control box can override the
platform control box at any time. If a person
operating the machine from the platform
becomes incapacitated, a person on the
ground can always take over machine
control.

The RT is not Electrically insulated.

Death or Serious Injury to operating
personnel, can occur if the machine should
come into contact with energized electrical
wires during operation.

■

Emergency Stopping

To stop an RT, push ei ther Emer gency Stop

switch, at any time on ei ther the ground con trol box

or the plat form con trol box and the en tire ma chine

stops and noth ing moves.

Figure 8.1 - Emergency Stop Switch at

Ground Control Box

Ground con trol box Emer gency Stop switch lo ca -

tion.

DO NOT attempt to operate the RT ground
controls if the platform, scissor assembly or
any other conducting part of an RT is in
contact with energized electrical wires or if
there is an immediate danger of such
contact.

NOTE

See the Electrical Hazard section, in this manual
for a complete explanation of the hazards
concerning electricity.

Operation Considerations

To use this chap ter, first de cide whether you will be

start ing and op er at ing the RT from the ground con -

trol box or the plat form con trol box.

Be gin at the sec tion en ti tled Op er at ing From The

Ground con trol Box if you in tend to start and run the

RT from the ground con trol box.

Be gin at the sec tion en ti tled Op er at ing From The

Plat form Con trol Box if you in tend to start and run

the RT from the plat form.

SR3370 & SR2770 – 13184A Rev A page 8 - 1

8. Operation

■

Fuel type

Af ter you have made the ground con trol / plat form
con trol de ci sion you need to know whether the RT
has a gas o line or die sel en gine. If it has a gas o line
en gine you fur ther need to know whether it is set up
to burn LP-only, or dual-fuel (LP or gas o line). If it is
set up to burn dual-fuel you have to de cide whether
to burn gas o line or LP. The sim plest way to tell
what kind of en gine set up you have is to look in the
fuel com part ment on the left side of the RT open
both fuel compartment doors.

●

If the only fuel source you see there is a
tank labeled GASOLINE FUEL, the RT
has a gasoline engine set up to burn
gasoline.

●

If the only fuel source you see is a tank
labeled DIESEL FUEL, the RT has a
diesel engine.

●

If the only fuel source you see is one or
more LP tanks, the RT has a special
gasoline engine set up to burn LP-only.

Figure 8.3

1.

Set the Battery switch  (see Figure 8.3) to
on.

●

If you see a GASOLINE FUEL tank and
one or more LP tanks, the RT has a
special gasoline engine set up to burn
either gasoline or LP.

Once you have de ter mined the type of en gine in ­stalled and the type of fuel you will burn you should
go to the cor re spond ing sub sec tion that ex plains
how to start that type en gine. Read the Ta ble Of
Con tents at the front of this man ual to see how the
dif fer ent sec tions and sub sec tions of this chap ter
are arranged.

Stabilisers

➜ If your ma chine is not fit ted with

sta bi lis ers you do not need to read
this sec tion.

NOTE:

Using the stabilisers.

The platform must be fully lowered to enable the
stabilisers to operate.

Once the platform is raised the stabilisers cannot
be set or adjusted.

Figure 8.19

2.

Set the Lift/Drive Selector  (see Figure

8.19) to lift (left).

NOTE

If the Lift Indicator Light  is not lit, the
platform will not go up because: the chassis is
not level, the stabilisers are not properly set, or
the articulating axles are not set. Correct the
problem then continue.

NOTE

The platform is about to move. If you have to
make an emergency stop, release the Joystick

Controller  and sharply strike the Emergency
Stop switch  straight in.

To make a nor mal stop, slowly move the Joy stick
Con trol ler  to its cen tered neu tral po si tion then
re lease it.

Before operating the stabilisers check to see that
the ground conditions under the four stabiliser
pads is firm, stable and unobstructed.

If the platform is up and the ground
compresses unevenly under different
stabiliser pads the RT might fall over
causing serious injury or death. Check the
level bubble frequently during operation. If
any movement of the bubble occurs,
immediately lower the platform and readjust
the stabilisers to re-center the bubble in the
ring.

When us ing the sta bi lis ers al ways check that all
four are firmly on the ground and that they are clear
of man hole cov ers, drains, etc., which may col ­lapse. If the ground is at all soft, steel plates at least
300mm x 300mm x 6mm should be placed un der
the feet to spread the weight.

Death or serious injury can result if an RT
tips over. Do not use the stabilisers to gain
extra working height, they are not designed
for that purpose. At least one of the
stabilisers should raise the RT above the
ground - use the other three to level the RT
as necessary.

The RT will not DRIVE un less all four sta bi lis ers
are com pletely raised i.e. If any one of the

Operating The Stabilisers Manually

❑ To set the stabilisers

1. The engine must be running and the RT set
for platform control box operation.

3.

Visually check the bubble level  to
determine which stabilisers must be further
extended to level the platform (see Figure

8.22).

NOTE

When the bubble  in the bubble level is in the
center of the ring , the platform is level.

4. Lower the appropriate stabilisers just enough

to center the bubble  (see Figure 8.22).
When the Lift Indicator Light  (see Figure

8.23) comes on, the platform can be safely
raised.

The Lift Enable Light  will illuminate if all
4 feet are in contact with the ground and the
machine is level.

4. If a stabiliser foot will not go down sufficiently
to make contact with the ground it is possible
that the cylinder has reached the end of its
stroke. Retract all stabilisers and put suitable
dunnage under the feet that did not touch the
ground and repeat step (2).

NOTE:

Manual or auto levelling is possible any time that
stabiliser movement is allowed. For example, the
machine can be manually levelled part way and
then auto levelled without the necessity of
retracting the stabilisers between the two
operations.

Emergency Operation Procedures

The fol low ing pro ce dures are emer gency pro ce ­dures only. DO NOT use them for nor mal op er a ­tion. Their pur pose is to get the plat form and
op er a tor safely to the ground when the RT will not
start or some other prob lem keeps the plat form
from low er ing in the nor mal way, or to move the RT
a short dis tance to a safe place when the mo tor will
not start.

There are three forms of emer gency op er a tion for
the RT.Emer gency stop, emer gency bleed-down,
and push ing.

Transporting

❑ Trailering

SRs weigh up to 3620kg (7964lbs)
depending on the model. Loading ramps
must be able to support that weight.
Transport trailers must be able to safely
transport that weight.

RT brake and drive systems are not
designed for grades over 35%. Drive slowly
and carefully on all slopes and loading
ramps.

To safely drive an RT onto a trans port trailer:

1. Visually inspect the alignment of the loading
ramp and the truck or trailer. They should
both be on the same straight line.

2. Set the RT ground control box for platform
operation.

3. Enter the platform and close the safety gate.

4. Use the platform controls to bring the RT into
the STOWED POSITION at the foot of the
loading ramp with the steering wheels
nearest the ramp.

5. Visually check (from the platform) to be sure
the RT is aligned with the ramp and the ramp
is still aligned with the truck or trailer. All
should be in a straight line.

Death or serious injury can result from
losing control of an RT during loading or
unloading. Always drive up or down a grade
with the Speed switch set to turtle (slow).

Bi-En ergy Option

This con sists of a com bi na tion of both a die sel en ­gine and a 24V DC mo tor to give a Bi-En ergy op ­tion.

Spe cif i cally, a 24V DC mo tor is mounted in the con ­trol cab i net. This pro vides an al ter na tive power
source to the die sel en gine.

The DC mo tor is pow ered by four "Deep Cy cle
Trac tion Bat ter ies" and has an au to matic bat tery
charger that is mounted in the con trol cab i net.

❑ DC motor

The DC mo tor lo cated in the con trol cab i net (see
Fig ure 11.1)

Af ter se lect ing the DC mode, turn the ig ni tion
switch to the ON po si tion (the sec ond po si tion of
the switch) at the ground con trol box (see Fig ure

11.3)

Figure 11.3 - Start Switch, Ground

When en ter ing the plat form turn the ig ni tion switch
to the ON po si tion (the sec ond po si tion of the
switch) at the plat form con trol box (see Fig ure

11.4).

Figure 11.1 - DC Motor

❑ DC motor operation

A Die sel / Elec tric switch, on the lower con trol box
(see Fig ure 11.2) is used to se lect ei ther the die sel
en gine or the DC mo tor.

If the die sel en gine [SWITCH UP] is se lected the
DC mo tor will not func tion and if the DC mo tor
(Elec tric) [SWITCH DOWN] is se lected the die sel
en gine will not run.

Figure 11.2 - Diesel/Electric Selection Switch

Figure 11.4 - Start Switch, Platform

Once the DC mode is se lected the mo tor will then
power all of the func tions in clud ing the sta bi lis ers in
the nor mal man ner. The only dif fer ence is that the
DC mo tor will only "run" when a func tion is se lected
e.g. rais ing the stack.

❑ Master battery isolater switches

There are two Mas ter Bat tery Iso la tor Switches
mounted at the end of the con trol cab i net (see Fig ­ure 11.5).

When the ma chine is not be ing used and is stowed
both of these bat tery iso la tor switches should be
turned to the "Off" po si tion.

When op er at ing with the die sel mo tor the 24V DC
bat tery iso la tor switch should be turned to the "Off"
po si tion.

When op er at ing the 24V DC mo tor the Die sel bat -
tery iso la tor switch should be turned to the "Off" po ­si tion.

The bat ter ies are en closed in a cab i net mounted at
the front of the ma chine. (see Fig ure 11.6)

The cab i net lid must be open whilst charg ing
to al low gas ses to es cape.

Lead-acid batteries contain sulphuric acid
which will damage eyes or skin on contact.
When working around batteries, ALWAYS
wear a face shield to avoid acid in the eyes. If
acid contacts eyes, flush immediately with
clear water and get medical attention.

Wear rubber gloves and protective clothing
to keep acid off the skin, if acid contacts the
skin, wash it off immediately with clear
water.

Lead-acid batteries produce flammable and
explosive gasses. NEVER allow smoking,

Troubleshooting

All of the ac tions de scribed in this chap ter may be
per formed by an RT op er a tor, a trained and qual i ­fied ser vice tech ni cian is not required.

The first col umn, of the fol low ing chart, lists some
com mon prob lems en coun tered byRT op er a tors.

The sec ond col umn lists some of the causes for
each prob lem. The third col umn lists rem e dies.

❑ Operator Troubleshooting Chart

Problem Cause Remedy

Engine will not start. Battery switch set to off. Turn battery switch to on.

Any problem that cannot be fixed by actions
listed below should be referred to a trained
and qualified RT service technician.

Emergency Stop
switch(es) not on.

Key switch set to off. Set the Key switch to on (the bar symbol).

Ground/Platform Selector
switch set to wrong
location.

Circuit Breaker tripped. Push the circuit breaker in.

Fuel switch not set
correctly.

Out of fuel.

Set the ground control Emergency Stop
switch to on (up). Also, if you are trying to
start at the platform control box you
should pull the Emergency Stop switch, at
the platform control box, until it pops out
(on).

If you are trying to start from the ground
control box, set the Ground/Platform
selector to ground (down). If you are trying
to start from the platform, set the selector
to platform (up).

If you are trying to start a dual-fuel engine
be sure the fuel switch is set to the correct
fuel.

DANGER:
Keep flames and lit tobacco away from
open fuel tanks.

Remove the cap from the gasoline or
diesel tank to see if there is fuel.

Check the gauge(s) on top of the LP
tank(s). If you are using LP gas, be sure
the valve on top of the tank is open.

Clogged air filter. Visually check the air filter gauge.

Engine oil too thick for
ambient temperature.

Stabilisers inoperative Platform not completely

down.

All systems sluggish. Hydraulic oil is too thick. Check for correct grade of Hydraulic Oil.

RT will not drive
forward or reverse.

SR3370 & SR2770 – 13184A Rev A page 13 - 1

Free-wheeling valve is
open.

Check engine oil chart in “Specifications”
chapter 3 for correct oil weight.

Completely lower the platform.

Allow time for machine to warm up.

Close the free-wheeling valve.

13. Operator's Troubleshooting

Problem Cause Remedy

Platform will not go up
or down.

Engine is not running. Start the engine from the control station

where you will operate the RT.

Switches set wrong
(Lift Indicator light is lit).

RT is not level.
(Lift Indicator light is not lit
and the Level Sensor
Alarm is sounding).

The Stabilisers are not
properly set.
(Lift Indicator light is not
lit).

For ground control operation:

Ground/Platform Selector = Ground

For platform control box operation:

Ground/Platform Selector = Platform
Lift/Drive Selector = Lift

Squeeze and hold the Safety Control then
push Joystick Controller forward to go up
or pull it backward to go down.

Use the stabilisers to level the RT.

If you are using the stabilisers, one or
more of them is not down quite far
enough. Lower each stabiliser a few
inches more to be sure each is firmly in
contact with the ground.

Platform will not drive
forward or reverse
when raised.

Unit not level.
Articulating axle operated.

If you are not using the stabilisers, one or
more of them is not fully up. Raise each
stabiliser completely up.

Situation normal, lower platform to drive.
